1.0 INTRODUCTION
<br /> On behalf of Forward Inc. (Forward),this report presents water quality monitoring data
<br /> generated during the fourth quarter 2012 monitoring period and also presents an annual
<br /> summary of the monitoring results for the 2012 monitoring year for the Forward Landfill
<br /> in San Joaquin County, California. Monitoring was performed in accordance with
<br /> requirements listed in the Central Valley Regional Water Quality Control Board
<br /> (RWQCB) Order No. R5-2003-0049. For reporting purposes, the water quality
<br /> monitoring network consists of two units: the Forward Unit and the Austin Unit. Section
<br /> I provides a description of the monitoring network, site inspections, and standard
<br /> observations; Sections 2 and 3 include discussions of water quality data for the Forward
<br /> and Austin Units, respectively. Section 4 provides the annual summary.
<br /> 1.1 MONITORING NETWORK
<br /> The water quality monitoring network at the Forward Unit currently includes 15
<br /> groundwater monitoring wells (five of which are dual depth well pairs), one domestic
<br /> well, two surface water monitoring stations, and 17 lysimeters (Figure 1-1). Monitoring
<br /> wells at the Forward Unit have been constructed to monitor groundwater at the facility as
<br /> follows:

<br /> WMW-D-01S, WMW-D-02
<br /> Note: Piezometers are sampled in the event that the"N'well in the dual depth well pairs is dry.
<br /> As presented on the following table, the monitoring network at the Austin Unit currently
<br /> includes 33 groundwater monitoring wells, two domestic wells, and two surface water
<br /> monitoring stations (Figure 1-1). The detection monitoring program(DMP) wells are
<br /> used to detect for a potential release from the landfill, while the corrective action program
<br /> (CAP) wells are used to evaluate changes in water quality and the effectiveness of the
<br /> corrective action measures. Of note,the 19 evaluation monitoring program(EMP) wells
<br /> were constructed as part of an on-going investigation and are not monitored under this
<br /> program. Monitoring points at the Austin Unit have been constructed to monitor the
<br /> groundwater/surface water at the facility as follows:
